EN 549 Standard

The EN 549 standard covers rubber materials for seals and membranes used in gas appliances and gas installation equipment. It specifies requirements and related methods for rubber materials used in gas installations, gas appliances, and gas devices in contact with flammable gases of the 1, 2, and 3 families of flammable gases classified in EN 437:2018, as well as natural gas, biomethane, and biogas of the same quality. The EN 549 standard also defines classification based on temperature range and hardness, applicable to materials used for producing homogeneous seals and homogeneous or reinforced membranes. The standard EN 549 should be applied to rubber products with a working temperature range from -40 to +150 degrees Celsius. This standard does not apply to silicone rubber products operating at nominal pressures above 200 hPa (200 mbar) or at temperatures below 0 degrees Celsius with gases from the 3 families. This is due to the potential for condensation. Products compliant with this standard confirm that the elastomeric sealing materials meet the requirements for use in gas installations and appliances. Each product should include information regarding the working temperature range. --- The BS EN 549:2019+A2:2024 standard sets requirements for the physical and chemical properties of rubber materials used for sealing and membranes in applications involving contact with flammable gases, including natural gas and LPG. Products meeting this standard ensure the highest safety, reliability, and performance standards. The updated version of the standard contains detailed information on elastomeric materials, including guidelines on mechanical strength, resistance to thermal aging, and gas permeation. **Key benefits of using rubber materials compliant with BS EN 549:2019+A2:2024:** - Gas permeation resistance - High tightness - Dimensional stability - Reliable durability under prolonged exposure to heat and chemicals At Power Rubber, we specialize in producing high-quality seals and rubber products compliant with the BS EN 549:2019+A2:2024 standard, ensuring dependable tightness and minimizing gas leakage risks, providing protection against hazards related to gas installation operation.
